Settings
Describes how to set application settings and a definition of the settings.
Application settings can be found within the appsettings.json file within the installation directory. This file defines various settings you can apply to Universal. Although you can edit this file directly, it's recommended that you use one of the following methods to persist settings as the appsettings.json file in the installation directory will be overridden on upgrades.
When installed from the MSI, the installation directory for PowerShell Universal is ${env:ProgramFiles(x86)}\Universal.
ProgramData AppSettings.json
You can create an appsettings.json file within the $Env:ProgramData\PowerShellUniversal folder. You can use a subset of the settings from within the appsettings.json file. For example, if you wanted to override the JWT settings, you could have an appsettings.json file like this.
1
{
2
  "Jwt": {  
3
    "SigningKey": "PleaseUseYourOwnSigningKeyHere",  
4
    "Issuer": "IronmanSoftware",
5
    "Audience": "PowerShellUniversal"
6
  }
7
}

Environment Variables
You can also set environment variables for your settings. Environment variables should have an underscore between each subset of the appsettings.json file. For example, if you want to change the JWT signing key via environment variable, you would set the variable $Env:Jwt__SigningKey. If you wanted to set the external API URL, you would set $Env:Api__Url.
Examples
Using an environment variable for the OpenID Connect secret.
1
$Env:Authentication__OIDC__ClientSecret = "mySecret"

Using an environment variable for JWT signing key.

$Env:Jwt__SigningKey = "mySigningKey"
